What is VDI?
The Physical World
Data security andcompliance are at risk.
One-off fixes are costly.Desktop refresh is
complicated and slow.
Applications conflict andimpact performance.
The Virtual World
Centrally control,track and secure data.
Centrally fix and deliver patchesglobally at a lower cost.
Rapidly update PCsor operating systems.
Isolate applications to improve performance and speed.
Virtualisation Layer
Hypervisor- Example • Runs directly on hardware• Manages resource
allocations• Strong fault and security
isolation• Encapsulation• Highly scalable architecture
• What’s available• vSphere• Microsoft Hyper V• Xen Server

Benefits
Desktop costs Purchase price £399 Maintenance £140 Half day to install £105
◦ £35 per hour Admin – 15 hours £525 Power usage £240 Total £1,409 Per annum
£352.25
VDI Costs Thin client £240 Maintenance £0 One hour to install £35
◦ £35 per hour Admin £0 Power usage £20 Back Office £265,000 £530 Total £825 Per annum £206.25
Cost per user model (500 users)
40.3% saving – payback 16 months
Real-World Financial Examples
What made VDI produce such high savings
Storage was the most expensive part of VDI and priced the solution higher thanPC’s. Thin provisioning from Citrix, VMware or Netapp has cut storage costs by 80%
Additional Incentives/BenefitsGreen Computing Initiative
Needs of a mobilised workforce
HA/DR for Desktop estate
Hardware Independence
Smooth the transition to Windows 7
Power Savings with Client Consolidation
Client Consolidation uses much less power than traditional desktop deployments
◦e.g. Assume 200 users Traditional desktop power consumption:
◦200 users X avg 300 watts per PC = 60,000 watts Client Consolidation power consumption:
◦3 x3850 = 6,000 watts + DS4700 = 1,000 watts + 200 Thin Clients x 5 watts = 7,000 + 1,000 = 8,000 watts
Cost savings is 260 watts per desktop
◦Estimated savings of £80 per PC per year! ◦ (assumes 10 pence per KW hour price for electricity).
Security Considerations
Secure Client device – End Point security
Connection to data centre - SSL VPN / Firewall
Secure virtual desktop – Hypervisor AV
No real physical savings for laptop users - YetLaptops can be replicated to backup virtual machineLaptop sometimes not needed (e.g. office to office)User can work from any locationThe Future :
◦Client Hypervisor with Secure Partition◦Online and Offline Access◦Bare metal Performance◦Synchronization

VDI and Remote Office Connectivity & Performance
Business Result:- No IT staff at remote locations- High speed access- Data is protected- “single instance of data”- Less hardware, licenses, storage, tape- None or less servers for branch office services- Data is safe!!
